Spotify's quest for worldwide audio domination took a big step forward today, after LG announced it has inked a deal to integrate the streaming music service in a range of connected media devices launching later this year. Early adopters won't be the only ones able to enjoy Spotify's cornucopia of on-demand tunage, however. LG also said owners of select connected media players currently available on the market will be able to download the Spotify app starting this April.

The Spotify integration is slated to show up in LG's Blu-ray players, home cinema systems, and smart TVs. You'll need a premium $10 per month Spotify subscription plan in order to stream to LG's devices, which will also get you ad-free songs, higher-quality audio, and mobile access through smartphone and tablet apps.

LG didn’t detail which new hardware will support Spotify, but the company noted integration on one of its as-yet unreleased 9.1 surround sound home cinema systems, the BH9530TW. As far as existing devices go, LG said its BH9430PW, BH7530TW, BH7430P, BH7130C, BH6730S, BH6430P, and BH6230S home theater systems will receive Spotify access in April, along with the company's BP730, BP630 and BP530R Blu-ray players. LG’s connected devices also include support for on-demand TV and movie services like Netflix, as well as access to YouTube, Facebook, and Google.

LG is not the first big home entertainment hardware manufacturer to partner with Spotify. Last year, the streaming music service struck a deal with Samsung to incorporate access on Samsung's line of E-series smart TVs, which prompted Spotify to create a new TV-optimized interface. The functionality on LG hardware will be similar to what’s available with Samsung devices, which includes access to 20 million on-demand songs, playlist support, basic radio functionality, and the ability browse and subscribe to friends’ playlists.

The likes of Samsung, LG and Panasonic have been trying to make their connected home entertainment devices more attractive to consumers by including access music and movie streaming services, and Spotify is a big player with around 24 million active global users and 6 million paid subscribers. In the U.S. alone, the company said it had passed 1 million paid customers last December.

Spotify has been on a roll in the past few days. First off, the company teamed up with Microsoft and The Echo Nest to launch Mixshape, a visual tool that sorts your playlists automatically based on the type and mood of the individual songs. Users manipulate a movable shape to rearrange a playlist based on tempo, and you can choose from various moods, such as romance, party, work or exercise. Spotify also launched its first ever paid advertising campaign this week.

Perhaps the most interesting development for Spotify is not music, though. The music streaming service is rumored be doubling-up on its offerings with on-demand video content, which could put it in direct competition with the likes of Netflix and Hulu. Spotify would have the advantage of an already established user base used to streaming media, so the company could offer a bundle of music and movies.
